Although Ling Feng exchanged for the submarine, he had to figure out how many robots this Expedition submarine needed to control, so he asked: "Taishan, let me ask you the most critical question, how many robots do you need to control this Expedition submarine now?" ”

Tarzan replied: "If you want to successfully control the submarine navigation, you need at least three robots of more than four generations, and among these three robots, one of them must be a robot of more than six generations as the main helm controller, and two or two of the fourth generation robots can perform other control tasks under its command." ”

Hearing this, Ling Feng frowned. "Then according to what you mean, then I still have to exchange two more fourth-generation robots?"

Taishan nodded and said, "Yes, those robots of your generation, whether they have reflexes or other abilities, are deficient, and they can't control this submarine to operate normally." ”

"Okay, then I'll exchange for two fourth-generation robots first, anyway, there are still less than 200,000 honor achievement points left, which should be enough." Ling Feng sighed secretly, and said in his heart, is it easy to exchange for a submarine to escape, and it cost 400,000 achievement points at once.

In the following time, Ling Feng spent 100,000 achievement points and successfully exchanged two fourth-generation robots, and now with one seventh-generation robot and two fourth-generation robots, his submarine used to escape finally gathered the personnel to control the voyage.

Now, Ling Feng's remaining honor achievement value is less than 100,000, and it seems that after returning to the south in the future. You have to hurry up and level up to fight monsters, otherwise, these achievement points will be exhausted sooner or later.

Originally, after exchanging submarines and robots, Ling Feng was ready to withdraw from the Infinite Arsenal, but after looking down and thinking about it, he felt that he still had to go to the exchange shop to take a look and see if he could find something cheap and useful.

Come to think of it. He immediately instructed the system, "Open the potion exchange area for me." I'd like to see if there are any other types of potions besides the ones that burst your lower potential. ”

Under his command, the picture of the giant display changed again, and then followed. A shop covered with various patterns of medicines and potions. appears on the display.

On top of those potion patterns. He saw the lower-level energy replenishment and lower-level potential explosion elixirs, but the exchange prices of these two potions didn't seem to be very expensive. Only 500 achievement points are enough. In addition, he also found a large number of other types of potions in these patterns, which he had not seen before, and he was not very clear about the properties of those potions.

However, there were a few other potions in the patterns of those potions that interested him very much.

"Intermediate Energy Replenishing Elixir, Exchange Price 1,000 Honor Achievement Points! Intermediate Potion Burst Elixir, Exchange Price 1,000 Honor Achievement Points! Superior Potion Burst Elixir ......"

After seeing these potions, Ling Feng finally understood that in addition to the lower-level potential burst elixirs, there were really middle-level potential burst pills and high-level potential burst pills, but the exchange prices of these potions were relatively high.

Intermediate strength and potential burst are both one thousand, like the high-level strength supplement and potential burst potion, their price is doubled, it is two thousand honor achievement points, that is to say, if Ling Feng wants to exchange for a high-level potion, he needs to spend four thousand honor achievement points.

However, what Ling Feng wanted to know more was what the effect of these intermediate and high-grade elixirs was? What is the difference between them and the inferior elixirs?

For this question in his heart, only Taishan can answer it for him in front of him.

Soon, Ling Feng learned about the effects and attributes of these potions from the robot Taishan, such as the intermediate energy replenishment potion and the potential burst potion, the effect of taking them is actually similar to the effect of the lower-level elixir, the only difference is that the lower-level potion has side effects after the effect is over, but the intermediate-level potion is useless. Moreover, after taking the intermediate drug, its effect will be 50% longer than the duration of the lower drug.

But like those high-level energy replenishment and potential explosion, these two high-level elixirs, their attributes and effects, are much more rebellious than those of mid-level elixirs.

The high-level potential burst potion, after taking it, can instantly increase the strength, speed, reflexes and defense of human beings by ten times, and the duration of the effect of the medicine is as high as more than an hour. What made Ling Feng even more excited was that the Superior Potential Burst Elixir had no side effects.

Therefore, he decided that if he accumulated enough achievement points in the future, he would exchange all of them for these high-level potions to use, and he would no longer be afraid of the side effects of any lower-level potions.

However, now that I've opened the potion exchange shop, I feel a little itchy if I don't exchange something.

Thinking of this, he immediately spent 20,000 honor achievement points to exchange for ten intermediate potions, and then used 40,000 achievement points to exchange for ten high-level potions.

After exchanging these things, in the end, the honor achievement points he had left were less than 30,000.

With the remaining honor and achievement points, he is ready to keep it for the high-energy battery, otherwise, it will be bad if the submarine runs out of batteries in the middle of the voyage.

After doing all this, Ling Feng chose to quit the Infinite Arsenal.

After appearing in the room out of thin air again, he looked at the time and found that it had only taken less than fifteen minutes to enter the Infinite Arsenal this time.

At that moment, after Ling Feng quickly packed up his things, he opened the door and went to see how the others were doing their preparations.

After taking a turn around the room of the macho man Xiao Yu He Hailong and others, I found that except for Fluttershy, everyone else was almost ready, and I have to say that no matter what time women are, they have to pack a little more than men, and it is a little more troublesome.

But it doesn't matter, because Chen Sanjie hasn't driven back yet, so Ling Feng and the others still have time to wait.

Half an hour later, Chen Sanjie finally drove back to the villa in the western suburbs, and as soon as he entered the door, he asked with a panicked face, "Ling Feng, what happened?" Why should I rush back? ”

Ling Feng stepped forward and patted him on the shoulder, shook his head and smiled bitterly: "This is a long story, anyway, you have to pack up your things immediately now and leave Yanjing with us!" ”

Hearing this, Chen Sanjie was even more puzzled. "What do you say? Leaving Yanjing? Where to leave Yenching? ”

"We want to return to the south, because we don't want you to be implicated by us, so you also want to return to the south with us!"

Ling Feng looked at Chen Sanjie apologetically, took a deep breath, and then told him everything that happened tonight, among them, Ling Feng specifically mentioned the matter of the Advent Day of December 17th.

After Chen Sanjie listened, he was so shocked that he couldn't speak for a long time, he sat on the sofa with a depressed face and thought about it for a long time, and finally he still chose to believe Ling Feng, so under everyone's urging, he began to go back to the room and pack up the simple luggage.

After Chen Sanjie finished packing his luggage, they hugged the twins of Huan Happy and Le, and then drove away from the villa in the western suburbs.

As for the servants and nurseries who stayed in the villa, Chen Sanjie had already overpaid them for a few months, and he also casually found an excuse to fool them into going back for a few days early tomorrow morning.

Ling Feng, Macho Man, Xiao Yu, Chen Sanjie, Luo Xiao, Xiao Fluttershy, plus He Hailong's father and son and the twins, these ten of them drove two Mercedes-Benz cars respectively, all the way to Yanjing East City, as long as they left Dongcheng, they could enter the boundary of Ludong Province after driving hundreds of kilometers ahead.

When the time comes, you can accelerate wildly all the way, and you can definitely arrive in Haimen County on the coast of Ludong before noon.

At this moment, Macho Man and Xiao Yu had a seizure because of the side effects of the drug, and they all fell asleep in the car, while Ling Feng was trying to stay awake and vigilant, he had been taking medicine to maintain his spirits.

As their car passed by Wangye Avenue in Dongcheng, Fluttershy suddenly called Ling Feng to remind her that the Jinhua Hotel where Chen Youyun was staying tonight was on this Wangye Avenue, and since they were passing by, should you say hello to her or say goodbye or something.

After Ling Feng listened, he was slightly silent for a moment, and finally asked Chen Sanjie to stop the car. (To be continued......)
